Deinosuchus is an extinct relative of the alligator that
lived 80 to 73 million years ago, during the late Cretaceous Period.
Measuring up to 40 ft and weighing up to 9.4 tons, its overall appearance
was fairly similar to its smaller relatives. It had large, robust teeth that
were built for crushing, and its back was covered with thick semispherical
osteoderms.
